TH REE-HORSE EVEN ER.

SPECIFICATION forming part of Letters Patent No. 417,091, dated December 10, 1889.

Application filed October 21, 1889. Serial No. 327,711. (No model.)

T all whom t may concern:

Be it known that we, HENRY G. REINEMER and ROBERT LANG, both of Pierronin the county of Bond and State of Illinois, haveinvented a certain new and useful Improvement Ain 'lhree-l-Iorse Eveners, of which the followsists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a detail perspective view of the tongue to which said self-adjusting center draft is attached; and Fig. II is an enlarged y,detail perspective, and shows the slot-bar that provides a free lateral scope to the side move ment of the triple and double trees and the whifetrees they carry.

Referrir g to the drawings, 1 represents the draft-tongue, details of which are` shown in' boththe figures.

2 is the surmounting-strap at the rear center-draft attachment, the rear end of which strap is secured to the tongue by the screwsaid strap and is seated in bolt 3, which passes through the bolt-hole 4 in e bolt-hole 5 in said tongue. Thedraftolt 6 passes through and is seated in the bolt-hole 7, neary the forward end of said strap, through a similarhole 8 in the rear center-draft-equalizing bar 9, through the anti-friction washer 10, that intervenes between. said tongue and said equalizing-bar, 'and through the draft bolthole 11 in said tongue.

The equalizing-bar U is preferably of steel, but may be of any other suitable material, and the said .draft-hole .7, by which it is pierced, is exactly one-third th'edistance from the stay and draft-chain hole 12 on the doubletree side of the attachment to that' also marked 12 at the other end of said equalizing-bar,so as to equalize the. draft between v.the three horses. Y

13V represents the stay and Idraft chains that connect the draft, respectively, froml the holes at each end of the center-draft-equalizing bar with the draft-hooks 14, whose straps 15 are respectively secured to the two ends of the tripletree 16 by the screw-bolts 17, which bolts pass through the bolt-hole 18 in said straps, through the tripletree, and through the parallel draft-straps 19 beneath said tripletree, the draft-chain from the short end of the equalizing-bar being hitched to the drafthook on the short end of the tripletree, and that from the long end of the bar being hitched tothe draft-hook on the long end of the tripletree. The Yparallel draft-straps 15 and 19, respectively, are provided with integral extensions, which at the short end of the tripletree embrace the middle of the doubletree 2O respectively'above and below, and at the long end of said tri pletree embrace the middle of the singletree 21, also above and below, for hitching the third horse. A bolt 22 passes through the `holes 23,'that register through the middle of the doubletree and ithroughnear the forward ends of the drafttree.

24 and 25 indicate, respectively, the upper and lower parallel draft-straps that couple the singletrees 21 of the two nigh horses to the doubletree to which they are secured, the said straps being attached to near` the ends of said doubletree and to the middle of said singletree, as are also the parallel straps that embrace the singletree of the third horse, by the bolts 26, that pass through the bolt-holes 27 ,in said respective coupling parts.

'lhe bolts 3, (i, 17,22,and 26 may be respectively secured and secure'tle parts' .that they couple by screw-nuts that are screw-seated on said bolts, or by any other suitable means.

28 represents the slotted guide-bar, that while restraining or holding down the tripletree from vertical displacement, yet allows free vertical movement within certain limits of said triplet ree and its draft attachments, so as to self-ad just variations in the side draft incident to thepassage of the team and harvester or other machine, &c., over inequalities ofthe surface of the ground. The fast end of said guide-bar is secured to the tongue by the screw-bolt 429, that passes through and is seated inthe bolt-hole '30 near said end of the guide-bar and` through said tongue, in

which seatit is secured by the screw-nut 3L A n anti-friction washer 32 intervenes between said tongue and nut. An inclined surmounting-shoulder 33 on said strap inclines upward from the tongue and then turns back to a horizontal position to forni the seat 34, on which the laterally-sliding tripletree Works.

35 represents an elongated slotv in the said seat of the guide-bar, in which slotworks the bolt 36, that; is seated-in the bolt-hole 37 in said tripletree one-third way from vthe draftbolt hole on the nigh end of said tripletree to that of the draft-bolt hole on the off end thereof, so as to equalize the draft between the individual horses that are respectively attached to the doubletree on the nigh side and to the separate singletroe on the olf side. The said bolt passes through slides within and is limited in its movements by the terminals of said elongated slot in said guide-bar,beneath which bar the bolt is held captive by `the screw-nut 3S. Anti-friction washers 39 and 40, respectively, intervene between the head of said bolt 36 and tripletree above and between the nut of said bolt and said guide-bar below.v

Now it will be seen that the centerdraft attachment is made and centralized far to the rear of the whiietrees, and at said rear attachment there is an equalizing-bar, and that by the use of our slotted guide-bar the triple, double, and single trees are held captive from vertical misadjustment, while they have at the same-time within certain necessary limits a free lateral swing, While the team with the harvester or other machine pass over inequalities in the surface of the ground, which elements of the invention" are of great advantage in effecting a precision of the work of its elongated slot, in which the triplet-reebolt 36 works, both hold the tripletree from vertical misadjustment and provides means for its free lateral self-adjustment within certain limits, but also,'as'said slottedl guidebar has a pivotal attaclunentby means of the pivot-bolt 29 to the tongue, the said slotted guide-barbas Withineertain limits a free selfadjusting pivotal movement that still further aids the self-adjustment of the whiiiletrees.

The draft-chains can bc adjusted to adiversity of lengths by changing thel h-itch on the draft-hooks it from one link to another on either or both the chains.

Our three-horse evener is att-achable and well adapted for the draft not only of harvesters, to which it has been described as es'- pecially adapted, but also to all classes of locomotive draft, such as to wagons, rollers, grain-drills, &c.

\Ve claim as our invention- 1. In a three-horse evener, the combination of the tripletree, the slotted guide-bar 28, and the bolt 36, that is seated in said tripletree and works in the slot of said guide-bar to restrain said triplctree from vertical displacement and allow within certain limits free lateral self-adjustment of the same, substantially as and for the purpose set forth.

2. In a three-horse evener, the combination of the tongue l, the center-draft-equali-zing bar 9, the draft-bolt 5, the tripletree, the draftchains that connect said equalizer to said tripletree, the slotted guide-bar 2S, secured to said tongue, and the bolL 36, that is seated in said tripletree and Aworks in the slot of said guide-bar, substantially as and for the purpose set forth. y

3.'In a th ree-horse evener, the combination of the center-draft-eqnalizing-bar 9, the bolted strap that surmounts and holds said equalizing-bar, the tripletree, the draft-chains thatv hold captive said tripletree to said equalizing-bar, the said chains being adjustable by transferei'iee of the hitch-links of the chains, the hooked upper draftstraps bolted to the tripletree to which said chains are hitched, the parallellower draft-straps, the double and single trees, and the parallel straps that attach said doubletree to its singletrees, the slotted pivoted guide-bar 28, the bolt by which said guide-bar is pivotally secured to the-tongue, and the bolt 36, that is seated in said'tripletree and works within the slot of -saidguide-bar, substantially as and for the purpose set forth.
